"The shutter glasses receive 3D frame display information and time information referenced to the master clock that corresponds to when frames are displayed. The shutter glasses control opening and closing of left and right shutters utilizing slave clock time and the received information."

"The shutter glasses and the display maintain synchronization when display and/or time information updates are skipped."

i think its shown that it would never be possible to use an ordinary usb-bt4 dongle as even samsung needed one with extra l-r-sync input lines
so even the glasses would be controllble via cheap dongles i doubt that we'll get acceptable syncing...
